[BUG] No sound on HP Spectre x360 13-aw2022ur (2020, Tiger Lake)

[aigilea]

Describe the bug
Both legacy driver and SOF driver only create devices for HDMI outputs, no speakers or headphones (or microphones). I've tried 5.8, 5.10 and 5.11 kernels with the latest 1.6.1 SOF distribution, the only difference is wording changed from dmic-related to soundwire-related around SOF initialization in dmesg.
PulseAudio refuses to init the card when SOF driver is enabled, playing sounds to /dev/snd/pcm* devices doesn't result in any output to speakers or headphones.
Laptop has the latest firmware (F.10 Rev.A) and there's no problem with sound in Windows obviously.
I'm running ubuntu, but according to the forum thread it's the same on Arch with the 13-aw2777ng laptop (it's basically the same hardware).

There's a wiki page on a similar 14-inch laptop describing some gpio trickery to enable the amplifier, but it assumes a functional pulseaudio with created sinks and so on. I've done that anyway to no avail -- pulseaudio still refuses to init and no sound is produced when playing to pcm devices.

There's ABI mismatch currently but I don't know where to get ABI3:18 SOF and the problem was the same with matching ABIs for both fw and topology.

Can you please fix that or point me in the right direction if you think problem is elsewhere?

I've also tried it with the latest userspace alsa lib, tools, fw and UCM, the only difference is the missing pcm name in the log

I can confirm this, same issue here on my HP Spectre x360 13-aw2777ng

[juimonen]

@bardliao @libinyang this seems to be soundwire device... any idea why we don't have pcm devices?

sof-audio-pci 0000:00:1f.3: No SoundWire machine driver found

The issue is that SOF driver can't find a suitable machine driver for this device. The driver will look up eg. snd_soc_acpi_intel_cml_sdw_machines[] to find a suitable machine driver.
So we have to add your device codec information to the corresponding acpi match table.
Please add below to /etc/modprobe.d/sof-dyndbg.conf and attach the whole dmesg output here. Create one if you don't have this file on your device.

options soundwire_bus dyndbg=+p
options soundwire_intel dyndbg=+p

And, please show me the result of lspci | grep '00:1f.3'

Thanks

[aigilea]

Attaching full dmesg with dyndbg.

From above, the codecs on your device is rt711 and rt1308.
But from below, your codec's information is not listed in the acpi table.

So, we have to add the codec information to BIOS at first. We need to figure out who can help on it. @mengdonglin

lspci | grep '00:1f.3'

0000:00:1f.3 Multimedia audio controller: Intel Corporation Tiger Lake-LP Smart Sound Technology Audio Controller (rev 20)

It is a TGL device and the match table is snd_soc_acpi_intel_tgl_sdw_machines[].
Looking at the table, we don't have a matched table for your device (rt711 on link 0 and 1 rt1308 on link 1), but fortunately, we have a similar configuration tgl_rvp. We should be able to enable SoundWire on your device with slight modification.
Below patch may help, but I have no chance to test it.

But, again, you have to fix the BIOS issue first. Alternative way is to add acpi table by yourself.
You can follow the guide to add additional acpi table.
A reference asl file is rtk_sdw_i2c.asl.
You don't need the I2C part. What you need is to add rt711 and rt1308 address into Scope (_SB.PC00.HDAS.SNDW)

Scope (_SB.PC00.HDAS.SNDW) {
	Device (RTK0) // RT711 on link0
        {
            Name (_ADR, 0x000020025D071100)  // _ADR: Address
        }
	Device (RTK1) // RT1308 on link1
        {
            Name (_ADR, 0x000120025D130800)  // _ADR: Address
        }
  

[aigilea]

There's some progress.
Now it looks better in dmesg, SOF initializes without errors, but the result is even stranger:
ls /dev/snd

seq  timer

I'm attaching the new dmesg and just in case dsdt.

upd.
I've re-checked if maybe I've somehow messed the particular kernel build up, but no, removing just the acpi patch turns everything back to errors in dmesg and a few files in /dev/snd with the same patched kernel.

[plbossart]

@aigilea thanks for testing. Can you try to add dynamic debug to sof_sdw ? when the probe remains silent, it's usually that the machine driver probe fails, and unfortunately we have no way to report this at a higher level.

[plbossart]

@bardliao I am wondering if we shouldn't add a hack where we use the adr for 701 for either RT711 or RT1308. The BIOS is broken, and if we don't get a fix we should have an indirection to the 'right' devices.

[aigilea]

@plbossart I've tried enabling dyndbg for sof_sdw.c, sof_sdw and sof_sdw* (but forgot to save that dmesg, I can redo this one if it may be useful). I haven't found any new information in dmesgs.
I've enabled dyndbg via kernel options, this morning it worked that way with atkdb.c so I guess it's ok. If it's not, I can redo any other way.

[plbossart]

@aigilea to be honest none of us on the Intel Linux team knew of the existence of HP devices with SoundWire, but that's indeed a real product. We can't expect everyone to override the DSDT, that's too invasive.

if you have spare cycles, can you try #2701 without the DSDT override? It should at least find the right devices but may fail later on.

I still need to confirm if there are one or two amplifiers on the link1, in the first case we are missing a topology configuration for mono amplifier.
